Important Factors to Consider – Energy Usage and Expected Yield

The consumption profile of your commercial building is key to the financial viability of the project. If you can provide us with a reasonable level of detail such as monthly electricity bills or half-hourly data from your electricity provider, then that is the starting point for us to do an evaluation for you. We can use this information to present meaningful data regarding the cost savings and financial payback achievable from a solar energy system.

We use industry leading solar design software, PV*SOL Premium, that enables us to analyse PV system sizing and yield potential. The yield is calculated by considering a number of different factors:

  • The efficiency of core components (solar panels and inverters)
  • The orientation and inclination of the PV array
  • The shading of the PV system from surrounding buildings and trees etc.
  • Local historic weather data

The Commercial Solar Landscape

Falling Costs

The uptake of solar PV across the World and the continued reduction in solar panel prices, have driven the cost of commercial solar installations to historic lows.

Positive ROI

The return on investment (ROI) of installing solar energy in larger kW commercial solar projects is now better than ever.

Mission to Net-Zero

A commercial scale renewable system is one of the most recognisable ways to reduce your company’s electricity bills and enhance your green credentials.

Did You Know?

Solar energy could account for as much as 20% of the UK’s total electricity generation by 2030.

Solar Products

Explore our range of solar products, carefully sourced from reliable manufacturers and fully certified to MCS standards, ensuring optimal performance and reliability. From advanced solar panels that harness sunlight, to cutting-edge battery storage systems, we provide practical solutions that lower costs and promote sustainability.

Commercial Solar Panel Maintenance

Solar PV systems are very reliable, but planned solar maintenance is essential to ensure continued high output efficiency. Many solar systems in the UK have been installed for several years now, some for over 5 years. Whilst most maybe running well, many owners don’t check their systems performance regularly and wouldn’t know if it was performing well or not.

Commercial Battery Storage

The ability to store excess electricity generated by solar panels and use it later at your convenience is a game-changer for businesses. It not only enhances your organisation’s energy self-sufficiency but also opens doors to significant cost savings. At Solar Voltaics, we’ve carefully selected two of the most advanced battery systems on the market, Tesla Powerwall 2 and GivEnergy.

Frequently Asked Questions

How do solar PV cells work?

Photovoltaic (PV) cells convert radiation from the sun into electricity.  A typical PV cell consists of a wafer of semi-conducting material, usually silicon, manufactured with two electrically different layers.  When sunlight hits the cell it excites the electrons within the silicon, creating an electric field across the layers and causing a flow of electricity.

How long do commercial solar panels last?

Commercial solar panels typically have a lifespan of 25-30 years. They continue to generate electricity beyond this period but at reduced efficiency.

How much electricity do solar PV systems generate?

An optimally orientated, un-shaded 1kWp array will, each year, generate approx 850kWh (units) of electricity.

What are the cost benefits of installing commercial solar panels?

Commercial solar panels can significantly reduce electricity bills, offering a high return on investment over time. The initial costs are offset by savings on energy bills and potential tax incentives. Moreover, solar energy’s predictability helps businesses budget more effectively by reducing exposure to fluctuating energy prices.

What size do solar PV panels come in?

PV systems are modular, allowing a great degree of flexibility in design and specification. The physical size of individual panels varies. Smaller output panels tend to be smaller in size and the very high output panels are much larger. The size of an array is determined by the available roof space and energy requirement of the property. We work with our customers to ensure that we provide a system that meets their requirements and available roof space.

Where can I place my solar PV panels?

Solar panels can be mounted in a range of locations, from a roof to the ground and even bespoke frames. We install on a range of roof types, including flat roofs. Ground mounted systems use ballast or specially designed mounting frames. Solar panels are best if they are south facing, but east and west facing roofs are are suitable, although output will be slightly less. A roof pitch of between 10 and 50 degrees is best and preferably with little or no shade. If shade cannot be avoided then we can include optimisers to reduce the shading impact.

What is the environmental impact of commercial solar panels?

Solar panels significantly reduce carbon emissions by generating renewable energy. This reduces a business’s carbon footprint and supports sustainability goals.

Do I need planning permission to install solar panels?

Most of the time the answer is no. However, if you live in a protected area such as an Area of Outstanding Natural Beauty or a National Park such as the South Downs, then you may need permission, but not always. We can advise you on this.. Some authorities will ask that you have a bat or bird survey first or that your system meets certain aesthetic criteria such as it being an ‘in-roof’ system where the panels sit flush with the roof tiles. We can work with your needs and design a system that meets the necessary criteria. Some new build properties may also have restrictions on what can be installed. In these cases, we recommend that you check with your estate management company.

The Business Case

Payback and Returns

A solar installation can offer a typical investment payback from 3 years onwards. The payback period depends on site electricity consumption and the retail price of electricity both now and anticipated in the future. If you provide us with a good estimate of your electricty useage and costs then we can overlay this with the expected output of the solar PV system to determine how much of the solar energy you are likely to use. It is the combinationof energy consumption profile and solar PV output that determines how useful a solar energy system will be to you.

PV systems require very little maintenance besides regular monitoring and replacement of inverters (5-10 years). In general, PV panels are self-cleaning unless your building is in an area that suffers from high dust levels, leaf fall etc.

Our Testimonials

View Our Google Reviews

    • From the initial call out Solar Voltaics couldn’t have been more helpful or professional. Mark came to visit the house several times and presented us with 6 options for solar panels. The work was prompt and the team polite and helpful. The electrician in particular was brilliant, and very diligent. Despite saying he would clock off early afternoon on the final day, when he discovered a problem connecting the battery he stayed until the job was resolved several hours later. We’ve since had other electricians in to look at other jobs in the house and they have commented on how good a job Solar Voltaics did. When we discovered one of the roof tiles hadn’t gone back correctly, the team came back to address this, despite the works being completed, which was very much appreciated. Would highly recommend.

    • Excellent Company, good price, excellent customer service, installers installed battery system with minimal mess, explained how to use it. All in all an excellent experience. I would not hesitate to use them again.

    • Great advice, Very professional and went the extra mile

    • They were great from start to finish and have continued to provide timely support post installation.
